<pre class="style1">Use Case UC07:&nbsp; Create Dynamic Configurations</pre>
<pre>&nbsp;</pre>
<pre><strong>Primary Actor</strong>:&nbsp; Configuration Designer</pre>
<pre>&nbsp;</pre>
<pre><strong>Stakeholders and Interests</strong>:</pre>
<pre>Simulation Operator:&nbsp; Depends upon the Configuration Designer to deliver coherent configuration files to the TraffoSim in order for the simulations to run properly.</pre>
<pre>TraffoPackets:&nbsp; Depend upon the makeup of the configuration to determine when they are sent to the TraffoBase as well as what the packet structure should consist of.</pre>
<pre>TraffoBase:&nbsp; Requires a working simulation to generate packets for the TraffoBase to store.</pre>
<pre>TraffoView:&nbsp; Requires a working simulation to generate packets that it will retrieve from the TraffoBase to analyze.</pre>
<pre>&nbsp;</pre>
<pre><strong>Preconditions</strong>:</pre>
<pre>System is installed and verified to be working properly.</pre>
<pre>&nbsp;</pre>
<pre><strong>Success Guarantee (postconditions)</strong>:&nbsp; 

Configuration files are created. </pre>
<pre>Configuration files are sent to the simulator.</pre>
<pre>&nbsp;</pre>
<pre><strong>Main Success Scenario (or Basic Flow)</strong>:</pre>
<pre>  1. Determine the type of mode to run in real-time or non-real time, from the SimulatorDynamicUI page.</pre>
<pre>  2. Select the &lsquo;Dynamic&rsquo; configuration from the SimulatorDynamicUI page.</pre>
<pre>  3. Select the pregenerated configuration or routing file.</pre>
<pre>  4. Enter your values for the 4 data parameters.</pre>
<pre>    a. Number of cars.</pre>
<pre>    b. Avg. Speed.</pre>
<pre>    c. Standard deviation of speed.</pre>
<pre>    d. Start time.</pre>
<pre>  5. Start the simulation.</pre>
<pre>  6. GUI sends generated configuration file to the Simulation Operator.</pre>

<pre>&nbsp;</pre>
<pre><strong>Extensions (or Alternative Flows)</strong>:</pre>
<pre>&nbsp;&nbsp; 1a.&nbsp; Invalid parameters.</pre>
<pre>&nbsp;&nbsp;&nbsp;&nbsp; 1.&nbsp; Stop simulation.</pre>
<pre>&nbsp;&nbsp;&nbsp;&nbsp; 2.&nbsp; Revaluate parameters.</pre>
<pre>&nbsp;&nbsp;&nbsp;&nbsp; 3.&nbsp; Restart Simulation.</pre>
<pre>&nbsp;</pre>
<pre><strong>Special Requirements</strong>:</pre>
<pre> - Installed and working TraffoSim system.</pre>
<pre>&nbsp;</pre>
<pre><strong>Technology and Data Variations List</strong>:</pre>
<pre>&nbsp; 1.&nbsp; Installed and configured TraffoSim, TraffoBase, and TraffoView systems.</pre>
<pre>&nbsp;</pre>
<pre><strong>Frequency of Occurrence</strong>:</pre>
<pre>&nbsp; Occurs with every new iteration of the dynamic configuration simulation.</pre>
<pre>&nbsp;</pre>
<pre><strong>Open Issues</strong>:</pre>
<pre>&nbsp; n/a</pre>
